ROTARY EXELOSION-ENGINE.

To allwhom if'ma y concern:

Be it known that I, ENRIQUE JUAN'CONILL, a citizen of Cuba, residing at1 Rue de Presbourg, Paris, in the. Republic of France.

5 have invented newanduseful Im rovements' which the on the main shaft,the piston rods havingeach a roller, which rollers by rolling in asuitable fixed path cause all of ,th

carried by the shaft to revolve.

The annexed drawings illustrate a form of explosion rotary engineconstructed according to the invention and comprising six cylinderseach' making two explosions for one revolution of the engine.

Fig. 5 shows dia ammaticall the form of the rollerpath 0 the engine. ig. 6 shows diagrammatically the form of the rollerpath and the arrangement of the cylinders of an engine with radialcylinders rotating with the shaft havi sixteen cylinders each makingfour explosions per revolution of the engine. Fig. 7 is a sectional 'ewshowing how the plates 5, i aresecured to the cylinder. 'Fig. 8 is asectional view showing how the 40 stamps u are supported, by the elementm;

The main shaft a has keyed to it a hexagonal drum or steel part?) onthesix faces of which are fixed by means of bolts the six cylinders a.Each. east inte ral therewith a segment of an annulus, al thesesegments, fixed together by means of bolts constituting ,a completeannulus. Each'piston 7 rice a roller g of steel or'other suitablematerial whichis loosely mounted on a stud f supported by two ears h hsolid with the piston. Each piston is further cut away according to twoplanes perpendicular to the axis of the engine and; moves between twoblades '5 21' secured to the cylinder by means of screw as seen. in Fig.2 and preventing mission ports of these cylinders has (Z is hollowed andcarw connected to a bronze contact w Patented Mar. 8,1910. i

the piston from turning on itself. The rollers g are adapted to rollagainst a roller path 9' formed of steel cast in one piece... Thisroller path can be fixed to any suitable frame or to the chassis of anautomobile. The rolling band on which bear the rollers of the piston isslightly projecting. The form of the roller path is determinedin suchmanner as to give the best output; to this end the parts of the rollerpath correspondmg to the compression are formed by gently slopingcurves, so as to give a slow and progressive compression, and the partscorresponding to the expansion are formed by rapidly sloping curves soas; to give a" very active expansion. 7

The casing is closed at the sides by two pieces of sheet-metal k iswhich have central apertures for allowing the rotation and cooling ofthe cylinders. These metal-sheets are secured by small bolts Z to therolling way 1. I

t The shaft a is carried by two bearing supports m, m, with four armsfixed. to the rolling way 9' by means of bolts. V

a -To each cylinder corresponds in the part b a chamber at extended bya'conduit oleading to the side of the distribution. During the rotationof the engine, the ports 0 pass successively in front of correspondingports p, g, p, q, of'thedistributing plate 7' (Fig. 4). The fresh gasesare supplied to the ad 72 by pipes s and the burned gases escape t roughpipes '25 leading to the exhaust ports 9, g. The distributing late 1'has two threaded stems a which sli e in' two corresponding holes of thebearing s'upport m. These stems tohold the plate 1n place and preventit'from revolving. Spiral springs a mounted on the stems u and bearingon the support on force the distribution plate 'bto bearenergetically'on the rotating part Into each chamber at corresponding toa cylinder projects the end of a sparking plug fixed to the periphery ofa circular eboniteplate 3/ securedto the drum 1); the six bronze contacts apass successively", during the rotation 105 in front of two smallbronze rollers z 2' mounted at the end of ebonite stems 1 articu- "ratedon pivots 2 carried by the casing; the. rollers a z are caused toib'eara ainst the plate 3 by means of a spring 3 an are elec- 110 tricallyconnected to one of the poles of a suitable source of electric current.In front of the plate y is mounted loosely on the main shaft anotherebonite plate 4: on which are attached two terminals 5' and 6 connectedto the second pole of the source of current. Two springs 7 and 8 fixedto the ebonite plate 4 carry two bronze rollers 9 and 10 against whichbear the teeth of a pinion 11 keyed on the main shaft; these teeth bymoving the springs apart through the medium of therollers, put them incontact with the 7 screws 5 and 6 and on leaving the rollers maximum theforce produced'for rotating the whole rotary part. The roller thus rollsup to B where the piston has come at the end of its stroke. The enginecontinuing to revolve on account of the speed acquired, the roller rollsup to C andforces the piston to return into the cylinder. During thistime the port 0 of the cylinder passes in front of the port g of thedistributing plate '2" and the exhaust of the burned gases is produced.From 0 to D centrifugal force alone work, takes causes the pistonto bearon said path and to cause the suction owing to the passage of the ort 0in front of the admission port p. At 5 the compression commences andlasts until A is reached. It is to be remarked that the compressionwhich is the stroke during which is produced the largest loss of laceslowly, and is produced almost entire y at the moment when anothercylinder is at its working stroke. This concordance assures a regularoperation of' the engine and almost entirely avoids the dead point. Whenthe roller of the iston reaches the point'A the ignition ro ler 2'touches the contact :0 corresponding to the sparking plug of thecylinder: the toothed pinion 11 in its rotation produces the spark, theexplosion is produced in the cylinder and the ogerations previouslydescribed are repeate It will be understood that the diametricallyopposed cylinders operate simultaneously: the result is that no .fiexionstrains are imparted to the motor shaft a and that each cylinder has twoexplosions to each revolution of the engine, the six cylinders thusgiving twelve explosions for each revolution. I

The advance of the ignition may be insured by turning in one directionthe ebonite plate 3/ by means of the rod'12 which slides in a sleeve 13fixed to the frame m. of the The present arrangement allows of doingaway with thecrank shaft, and of dispensing with the fiy-wheel, the massof the moving cylinders taking its place: further, inders are,

that overheating need not be feared and the use of radiators will beunnecessary.

In Fig. 6 is illustrated dia 'rammatically by way of example a form oiengine based on the same principle as the one described but havingsixteen cylinders instead of six.

The explosion is produced simultaneousl at four points A that is to sayin four cy inders at the same time and four times per cylinder and perrevolution. Between two successive points A each cylinder accomplishes acomplete cycle: from A to B useful work; from B to C exhaust; from C thecyl on account of their rotation, in contact with constantly renovatedair, so

to D suction and from D to A compression and i nition.

Each cylinder giving,

four explosions per revolution, there is thus for the sixteen cylinders,sixty four explosions per revolution. The distributing plate has in thiscase four admission openings and four exhaust openings. The engine is inthis case very regular, the dead points are avoided and on account ofthe continuity of the engine efforts, the respective dimensionsv of allthe parts may be very much reduced, 1

which gives a great lightness with a great regularity.
